Save Draft and Preview buttons all of a sudden gone

I was in the middle of typing a post and went to save the draft & all of a sudden the button was gone…..thinking maybe it saved automatically, closed the screen, but it didn’t save. Now when I pull up any of my drafts the buttons are gone.
I searched the threads and tried everything I saw to try:

Disabled all my plug-ins (didn’t work, so I re-enabled them)
Reset my theme to default (didn’t work so I set it back)
Cleared cache & cookies from my browser (I’m using an ipad with safari if that makes a difference)
Went back & forth between the 1 & 2 columns
Closed out of all screens & brought it up again–the button is gone on my browser & my app

They still aren’t there–sorry if I’m missing something obvious, sort of new to this, but have many posts started & never had this happen. The weird thing is I wasn’t changing anything in terms of settings or anything else all day, just typing in posts & all of a sudden unable to save.
